DA Form 4309-1: US Army Marine License (Pocket) Guide – DA Form 4309-1, officially titled the United States Army Marine License (Pocket), serves as the wallet-sized credential verifying that a Soldier has met the qualification requirements to operate or serve in specific positions aboard U.S. Army watercraft. It is issued by the Maritime Qualification Division (MQD) of the U.S. Army Transportation School at Fort Eustis, Virginia (ATTN: ATSP-OCT, Fort Eustis, VA 23604-5000).
This pocket license complements the wall version (DA Form 4309) used primarily for warrant officers and works alongside the U.S. Army Marine Certificate (DA Form 5673). It confirms vessel-specific qualifications and endorsements for roles in Army watercraft operations.
Importance of the US Army Marine License (Pocket) for Soldiers
The DA Form 4309-1 is essential for Soldiers in maritime Military Occupational Specialties (MOS) such as 88K (Watercraft Operator) and 88L (Watercraft Engineer), as well as certain warrant officer MOS like 880A (Marine Deck Officer) and 881A (Marine Engineering Officer). It proves that the holder has completed the necessary training, examinations, and vessel-specific tasks to safely perform duties aboard Army vessels.
For U.S. Army personnel operating watercraft—ranging from small boats to larger intratheater vessels—this license is a key credential. It supports operational readiness, career progression, eligibility for assignments, and potentially career sea pay. It aligns Army standards with broader maritime safety and proficiency requirements.
How to Obtain DA Form 4309-1?
Obtaining the pocket license involves these main steps, governed by Army Regulation (AR) 56-9, Watercraft Operations:
- Meet Prerequisites: Soldiers must satisfy physical, medical, and character standards, maintain a valid sea service record (often via DA Form 3068-1), and complete required training.
- Complete Vessel-Specific Training: This includes the Deck Proficiency Training (DPT) or equivalent for the assigned watercraft and position.
- Pass Examinations: This typically involves the Marine Technical Examination (MTE) for certification levels.
- Unit and MQD Process: The unit administers training and forwards documentation to the Maritime Qualification Division (MQD) at Fort Eustis. MQD reviews, validates, and issues the DA Form 4309-1 with appropriate skill-level endorsements.
Training occurs primarily through the Maritime Intermodal Training Department (MITD) at the U.S. Army Transportation School.
Eligibility and Requirements for Army Mariners
Eligibility generally requires:
- Assignment or anticipated assignment to Army watercraft duties.
- Successful completion of proponent school training (e.g., for 88K or 88L MOS).
- Passing relevant examinations and practical assessments.
- Meeting ongoing physical and professional standards.
Warrant officers (e.g., 880A/881A) follow additional pathways, including advanced certification courses. The license is issued per skill level with vessel-specific endorsements.
Validity, Renewal, and Revalidation of DA Form 4309-1
The US Army Marine License (Pocket) remains valid for the period of continuous vessel-specific assignment, provided the associated U.S. Army Marine Certificate (USAMC) has not expired. Key rules include:
- Annual Revalidation — Complete designated DPT tasks on or before the anniversary date.
- Expiration — It expires one year after departure from the vessel or USAMC expiration.
- Renewal — Aligns with USAMC renewal (typically every 5 years).
Soldiers returning to a position within one year may revalidate more easily. Failure to maintain qualifications can affect MOS status and assignments.
Suspension, Revocation, and Administrative Actions
Commanders or vessel masters can request suspension or revocation for cause (e.g., safety violations, incidents, or misconduct). Temporary suspensions (up to 120 days) allow for investigation. MQD and higher authorities, including the Chief of Transportation, handle formal actions. Revocation typically requires reapplication as an original license.

Why This Matters for U.S. Army Personnel?
For active duty, Reserve, and National Guard Soldiers in watercraft roles, the DA Form 4309-1 represents verified expertise in maritime operations. It supports mission success in logistics, transport, and expeditionary operations while opening pathways to credentials recognized by civilian maritime authorities (e.g., toward U.S. Coast Guard Merchant Mariner Credentials via MITD programs).
Soldiers seeking information on training, licensing, or records should contact the Maritime Qualification Division or the Maritime Intermodal Training Department at the U.S. Army Transportation School, Fort Eustis, VA.
